NOTE:
Delamination of the diesel fuel tank can occur resulting in
a loss of power due to debris (silver flakes) clogging the fuel
filters. In some cases the fuel injection pump and/or fuel injectors
have also been damaged. Ford has issued a service bulletin (#19728)
addressing this concern. This issue can affect all diesel 1999-2010
E-350, F-350, F-450, F-550, F-650, and F-750 Super Duty models.
This will probably not be covered by factory warranty and will
cost you thousands if you do not replace your factory tank before
problems start! Ford does not have a fix for the tank, and it
will have to be replaced with another steel tank destined to
fail.

40
Gallon*, extra heavy duty, frame mounted, after-axle replacement
tank for F-350, F-450, and F-550 Narrow Frame, Cab and Chassis
vehicles for model years 2011-2015. Tank is constructed of
military grade cross-linked polyethylene (XLHDPE). Compatible
with most bio-diesel fuel. Tank solves the problem of lining
failure and corrosion in steel OEM tanks caused by fuel quality
issues which can lead to extremely expensive fuel system repairs.
Tank is light in weight, corrosion-proof, extremely durable
and features a drain plug for easy maintenance. Complete with
rollover vent valve, and stainless steel interior flanges.
